Question

A block of mass 4 kg is kept at origin at t
= 0 and is having velocity 4V5 m/s in
positive x-direction. The only force acting
on it is conservative and its potential
energy is defined as
U (x) = – x3 + 6x² + 15 (SI units).
Its velocity (in m/s) when its acceleration
is minimum after t = 0 is​
